A researcher is 95% confident that the interval from 2.9 minutes to 6.83 minutes captures w = the true mean amount of time mice take to complete a maze for a piece of cheese.
Is it plausible that the true mean number of times for all mice to complete this maze may be less than 7 minutes?
O No, this is not plausible for the population mean because 7 minutes is within the 95% confidence interval
No, this is not plausible for the population mean because 7 minutes is not within the 95% confidence interval.
Yes, this is plausible for the population mean because 7 minutes is not within the 95% confidence interval.
Yes, this is plausible for the population mean because the upper boundary of the 95% confidence interval is below
7 minutes

step-by-step explanation:

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
